The technical field to which the invention relates
Embodiments of the present invention relate to methods of reducing virus titers in vivo and treatment of patients with viral respiratory infections. Embodiments of the present invention also include methods of treating influenza infection, including influenza, especially H1N1. In addition, embodiments of the present invention relate to methods for treating the above infections with the use of injected intranasally, and/or intravenous and/or entered by the inhalation of recombinant human protein S.
The level of technology
Protein of Clara cells with a molecular weight of 10 kDa (SS) or uteroglobin (UG) is a small homodimeric secretory protein produced by certain epithelia of the mucous membranes and other organs of epithelial origin (Mukherjee, 1999). Protein S consists of containing 70 amino acid residues of two identical subunits, each of which is the leitmotif of the secondary structure forms a "chetyrehspalnyh node, connected in anti-parallel orientation of the two disulfide bonds between cysteines 3 and 69', 3' and 69 (Matthews, 1994; Morize, 1997). Protein S - the first representative of a growing family of small globular proteins with the same secondary, tertiary and even�artichow patterns and, believed to perform similar functions. It turns out that his primary form is C) an homodimer, containing two disulfide bonds. In humans, the main place of production of the protein S are easy, although some of the other bodies are synthesized small amounts of mRNA that encodes this protein (Singh, 1987; Sandmoller, 1994). Protein S is an anti-inflammatory and immunomodulatory protein that has been characterized by its various interactions with other proteins, receptors and cell types (see review in Mukherjee, 1999, and Pilon, 2000). The decreased levels of the protein products SS or mRNA were detected in different tissue samples and biological fluids in a wide range of disease States characterized by some degree of inflammation, including pneumonia (Nomori, 1995).
Physiology of protein S in different types of pulmonary infection was investigated in one line of mice with a knockout of protein S. In two studies, mice with a knockout of protein S and mouse wild-type were infected with two typical human respiratory pathogens - Pseudomonas aeruginosa, or adenovirus. The knockout mice were found more rapid disappearance of pathogens with greater neutralization of pathogens is the innate immune system, which suggested the use of protein deficiency S during viral and bacterial �Peccei (Hayashida, 1999; Harrod, 1998). This is consistent with earlier observations, in which it was observed that the protein S is immunosuppressive agent (Dierynck, 1995; 1996). This indicates that the protein S able to suppress the natural immune response to infection, bacterial or viral, including influenza. Therefore, you should not expect that the introduction of the protein S in the presence of viral or bacterial respiratory infection benefit the patient. Subsequently, it was noted that recovery of function S in knockout mice using recombinant human protein S (rhCC10), inserted before infection with respiratory syncytial virus (RSV), leads to faster disappearance of the infection than in knockout mice without such reduction (Wang, 2003). However, recent studies have shown that rhCC10 protein can prevent the development of acquired immunity, particularly the emergence of antigen-specific T cells, when present simultaneously with the interaction of antigen with dendritic cells (Johansson, 2007). This again indicates that the introduction of rhCC10 protein may not be useful for a patient with an infection. Thus, in present knowledge concerning potential hazards or use applications rhCC10 protein for the treatment of respiratory infections, contradictory and do not allow to draw conclusions �otnositelno safety and/or effectiveness of the use of protein S to treat various types of respiratory infections. There is no information concerning the action of protein S for influenza infections. In this application is described: a direct test of the effectiveness of rhCC10 protein of influenza type A in vivo, a direct test of antiviral effect of protein S at the cellular level, the mechanism of its action and its possible application for the treatment and/or prophylaxis of viral infections, in particular influenza infection.
The flu virus over the last 120 years was the cause of the four major outbreaks (1889, 1918, 1957 and 1968), led to the deaths worldwide, about 50÷100 million people. The flu virus is orthomyxovirus, RNA-containing virus that is transferred by aerosol and by direct contact of infected surfaces to the mucosa of the nose and infects epithelial cells of the respiratory tract. Influenza infection can cause severe symptoms, including fever, sore throat, muscle pain, malaise, weight loss, respiratory congestion, and in some cases respiratory failure and death. The flu causes the acquired immune response (cytotoxic T-cells and antibodies), which is usually the normal healthy individuals eliminates infection within 1÷2 weeks. Some subtypes of influenza infecting humans, including avian flu (H5N1), seasonal influenza (H3N2) and swine flu (H1N1) may locationcalifornia means, such as neuraminidase inhibitors. However, the high mutation rate of influenza virus has led to the emergence of strains of drug-resistant (Moscona, 2009), so the widespread use of antiviral drugs for the prevention and/or treatment will accelerate the development of resistance to these drugs. Therefore, for the treatment, cure and prevention of influenza infection is a need for new therapeutic agents. Also, there are no approved therapies for the vast majority of viral infections of the respiratory tract or other body systems.

Reproduction and determining the titer of influenza virus
Prepare strain A/PR/8/34 influenza virus A (H1N1), purchased from American Bank of type culture (American Type Culture Collection, Manasass, Virginia, USA). The influenza virus propagated in MDCK cell cultures (number CCL-34 catalog of ADS) by infecting a monolayer of cells at the stage of 60% of the merger (in vials with a volume of 150 cm2) influenza virus at a multiplicity of infection (MOI) of 0.01. After 3 or 4 days, when developed cytopathic process and most of the cells separated from the surface of the vessel, remove cells and the supernatant. The cells removed by centrifugation (800 g), nodosa�full-time the liquid is filtered (pore size 0.45 μm) and centrifuged (18000 g) for 2 hours at 4°C to precipitate the virus. Precipitate the virus was resuspended in DMEM, the suspension was divided into aliquots and stored at -150°C. the Titer of influenza virus is determined by placing 0.1 ml of serial dilutions of viral samples in monolayers of MDCK cells in a plate of 96 cells cultured in the presence of 0.1% bovine serum albumin (BSA) and trypsin. After 3 days register cytopathic effect and is determined by the method of Kärber dose 50% infection in tissue culture (TCID50).
Processing of lung tissue for analysis of viral load
Aseptically remove sections of the left and right lobes of the lungs of infected mice hamsters and cotton, weighed and homogenized in 1 ml DMEM for 45 s, using the machine to destroy tissue (Biopspec Products Inc., model 985-370) in mode 5. The homogenates was centrifuged at 3000 g for 20 min, the Clarified supernatant is collected and stored at -150°C until use.
Determination of virus titers
The titers of the virus stocks of the virus and multiplied in homogeneo lungs determined by serial dilution followed by analysis of blackarachnia (PFA) or analysis of foci formation (FFA). The number blakebrough units (the FIGHT) and forming foci units (OUE) in 1 ml of the original sample is calculated before the start of the study. Retain one set of samples of the virus sufficient for the PFA and FFA, and after�stop studies determine the number of FIGHTS and AOE. Serial dilutions of cultured virus in clarified medium (DMEM with 1% BSA) were prepared in the range of dilutions from 101up to 108. Each dilution characterize using PFA and FFA. For cultured influenza virus usually get credits 107-109The FIGHT/ml.
Intranasal introduction rhCC10 protein to reduce pulmonary virus titer of influenza
Cotton hamsters (S. hispidus), a kind vole is an animal model in which the influenza virus replicates and causes a mild respiratory infection (Ottolini, 2005). Animals infect by intranasal inoculation of influenza virus and pulmonary virus titers reached a maximum after 2 days (about 48 hours) after inoculation. This model is used to identify compounds that inhibit replication of influenza virus in vivo.
Not containing pathogens of cotton hamsters were obtained from Virion Systems, Inc. (Rockville, MD). Only 18 cotton hamsters (S. hispidus, age 6-8 weeks) were infected with influenza virus type A (A/PR/8/34), the H1N1 strain by intranasal inoculation, the dose for each animal was 107TCID50in a volume of 0.1 ml. of Six animals were given a placebo (0.9% NaCl), six animals were injected with 0.5 mg/kg rhCC10 protein and six animals were injected with 5.0 mg/CT rhCC10 protein by intranasal installation 2 hours before inoculation of the virus. Animals were scored on the second day after infection,�GDSs titers of virus are usually the most high, and in lung tissue was determined by viral load. Fig.1 shows the reduction in virus titer in the lung tissue that was observed in both groups that received a dose of rhCC10 protein. The titer of virus in the lungs is expressed in units of (×107) TCID50/gram of tissue.
Systemic administration of rhCC10 protein to reduce pulmonary virus titer of influenza
Only 18 cotton hamsters (S. hispidus, age 6-8 weeks) were infected with influenza virus type A (A/PR/8/34), the H1N1 strain by intranasal inoculation, the dose for each animal was 107TCID50in a volume of 0.1 ml. of Six animals received placebo (physiological saline solution), six animals received 0.5 mg/kg rhCC10 protein and six animals received 5.0 mg/kg rhCC10 protein by intraperitoneal injection. Intraperitoneal route of administration provides a significant amount of circulating rhCC10 protein and mimics intravenous people. Each animal received a total of 6 doses of either placebo or rhCC10 protein approximately every 12 hours, including two doses (morning and evening) the day before infection, two doses per day of infection and 2 doses the next day after infection (3 doses before infection and 3 doses after infection). Animals were scored on the second day after infection, when virus titers are usually the most high, and in the lung tissue were determined by viral load. Fig.2 illustrates with�tistichesky a significant reduction (p< 0.01) and the titer of virus in the lung tissue, found in the group with the dose of 5 mg/kg rhCC10 protein, and a trend of decrease in viral titer in the group with a dose of 0.5 mg/kg. virus Titer in the lungs is expressed in units of (×107) TCID50/gram of tissue.
Based on the above, it was found that rhCC10 protein reduces the titer of virus in respiratory infections. This indicates the possibility of using rhCC10 protein to treat, cure and/or prophylaxis of influenza infection. In accordance with embodiments of the present invention provide based on rhCC10 protein therapy with intranasal and intravenous or combination thereof, effective to treat, cure or prevent influenza infection.
The suppression of virus replication at the cellular level with the use of SS
Cells Ner ADS, Manassas, VA) were used for propagation of the virus RSV, strain A-2 (Advanced Biotechnologies, Inc., Columbia, MD), and obtaining a working viral drugs. Cells were sown in the amount of 50000 cells per cell in tablets of 48 cells and were grown in minimal medium eagle (MFM) with 10% serum embryo calves (FBS) to approximately 80% confluence. Cells pre-treated with protein S in 0.5 ml MEM for 4 hours. Then the medium was replaced by fresh one and the cells were infected with virus RSV in a dose of 1×106TCID50a Cup for cell cultures d�NetRom 100 mm for 1 hour. Neadsorbirovanne virus was removed by washing and added to 0.5 ml of medium MEM with 2% FBS, 4 mm L-glutamine and rhCC10 protein. Supernatant was collected on the fourth day after infection and virus was titrated. Fig.3 shows that the protein S at a concentration of 1 mg/ml almost completely eliminates the production of virus RSV, and at doses of 100 and 300 µg/ml was observed approximately 3-fold reduction.
Protein S also inhibited viral replication in the cells, if it was administered after 1, 24 and 48 hours after infection. Fig.4 shows that rhCC10 protein effective in suppressing the titer of the virus when administered not only before infection, but also after infection. This is the first direct evidence of antiviral activity of protein S at the cellular level and illustrates the potential benefits rhCC10 protein as a means of antiviral therapy in the treatment after infection.
The mechanism of the antiviral action of protein S
The phenotype of epithelial cells of the respiratory tract in mice with a knockout for S shows that in the absence of protein S distribution of intracellular organelles abnormally that there was an anomalous way starannie membrane structure and violation of the secretion of other proteins produced by the cell. The authors suggest that this phenotype indicates that the protein S plays an active role in the transport of secretory vesicles from �of Parata Golgi to the plasma membrane of cells. Protein S also modulates the capture and processing of antigens to antigen-presenting cells. The authors suggest that these observations indicate that protein S is an important factor in the transport of materials both outside and inside many cell types. From this the authors conclude that protein S suppresses viral replication, preventing the transport of the virus into the cell. Since all viruses use cellular processes transport for introduction into the cell and replication, it should be expected that protein S can suppress the replication of all viruses. You can also expect that other secretogranin having a structure similar to a squirrel SS, also inhibit viral replication at the cellular level. Similarly, we can expect that obtained from protein S and other secretagogues, modulating cellular processes transport peptides are also able to suppress viral replication.
